Later this week, President Barack Obama will stand on the field of Bank of America Stadium here and deliver his acceptance speech that ends the Democratic National Convention. The stadium, located in downtown Charlotte, sits in the shadow of corporate skyscrapers like the Bank of America Corporate Center and the Duke Energy Center. Financial services employees can walk to the stadium and the bars around it from pristine apartment complexes located nearby. Others can get to it by a brand new light rail line that runs to the city’s southern suburbs.
